Dual Directional Trigger Participation Securities Based on the Value of the Worst Performing of the Russell 2000® Index and the S&P 500® Index due September 5, 2025
Fully and Unconditionally Guaranteed by Morgan Stanley
Principal at Risk Securities
The Trigger Participation Securities, or “securities,” are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. The securities will pay no interest, do not guarantee any return of principal at maturity and have the terms described in the accompanying product supplement for participation securities, index supplement and prospectus, as supplemented or modified by this document. The payment at maturity on the securities will be based on the value of the worst performing of the Russell 2000® Index and the S&P 500® Index. At maturity, if the final index value of each underlying index is greater than its respective initial index value, investors will receive the stated principal amount of their investment plus a return reflecting 100% of the upside performance of the worst performing underlying index, subject to the maximum upside payment at maturity. If the final index value of either underlying index is less than or equal to its respective initial index value but the final index value of each underlying index is greater than or equal to its respective trigger level, investors will receive the stated principal amount of their investment plus a positive return based on the absolute value of the performance of the worst performing underlying index, which will be effectively limited to a 30% return. However, if the final index value of either underlying index is less than its respective trigger level, the absolute return feature will no longer be available and instead investors will be negatively exposed to the full decline in the worst performing underlying index and will lose 1% for every 1% decline in the worst performing underlying index over the term of the securities. Under these circumstances, the payment at maturity will be less than 70% of the stated principal amount and could be zero. Accordingly, you may lose your entire investment. Because the payment at maturity of the securities is based on the worst performing of the underlying indices, a decline in either underlying index to less than its trigger level will result in a loss of a significant portion or all of your investment, even if the other underlying index has appreciated or has not declined as much. The securities are for investors who seek an equity indexbased return and who are willing to risk their principal, risk exposure to the worst performing of two underlying indices and forgo current income and upside above the maximum upside payment at maturity in exchange for the participation and absolute return features that in each case apply to a limited range of performance of the worst performing underlying index. Investors may lose their entire initial investment in the securities. The securities are notes issued as part of MSFL’s Series A Global MediumTerm Notes program. All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These securities are not secured obligations and you will not have any security interest in, or otherwise have any access to, any underlying reference asset or assets.

Investment Summary
Dual Directional Trigger Participation Securities
Principal at Risk Securities
The Dual Directional Trigger Participation Securities Based on the Value of the Worst Performing of the Russell 2000® Index and the S&P 500® Index due September 5, 2025 (the “securities”) can be used:
￭To gain exposure to the worst performing of two U.S. equity indices, subject to the maximum upside payment at maturity
￭To obtain a positive return for a limited range of negative performance of the worst performing underlying index
￭To provide limited protection against a loss of principal in the event of a decline of either underlying index as of the valuation date but only if the final index value of each underlying index is greater than or equal to its respective trigger level
If the final index value of either underlying index is less than its respective trigger level, the securities are exposed on a 1:1 basis to the percentage decline in the worst performing underlying index over the term of the securities. Accordingly, investors may lose their entire investment in the securities.
Maturity: 
Approximately 4 years 
Participation rate: 
100% (applicable only if the final index value of each underlying index is greater than the respective initial index value) 
Maximum upside payment at maturity: 
$1,350 to $1,400 per security (135% to 140% of the stated principal amount). The actual maximum upside payment at maturity will be determined on the pricing date. 
Trigger level: 
With respect to each underlying index, 70% of the respective initial index value 
Coupon: 
None 
Listing: 
The securities will not be listed on any securities exchange 
The original issue price of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date will be less than $1,000. We estimate that the value of each security on the pricing date will be approximately $940.70, or within $45.00 of that estimate. Our estimate of the value of the securities as determined on the pricing date will be set forth in the final pricing supplement.
What goes into the estimated value on the pricing date?
In valuing the securities on the pricing date, we take into account that the securities comprise both a debt component and a performancebased component linked to the underlying indices. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying indices, instruments based on the underlying indices, volatility and other factors including current and expected interest rates, as well as an interest rate related to our secondary market credit spread, which is the implied interest rate at which our conventional fixed rate debt trades in the secondary market.
What determines the economic terms of the securities?
In determining the economic terms of the securities, including the participation rate, the trigger levels and the maximum upside payment at maturity, we use an internal funding rate, which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the securities would be more favorable to you.
What is the relationship between the estimated value on the pricing date and the secondary market price of the securities?
The price at which MS & Co. purchases the securities in the secondary market, absent changes in market conditions, including those related to the underlying indices, may vary from, and be lower than, the estimated value on the pricing date, because the secondary market price takes into account our secondary market credit spread as well as the bidoffer spread that MS & Co. would charge in a secondary market transaction of this type and other factors. However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 6 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying indices, and to our secondary market credit spreads, it would do so based on values higher than the estimated value. We expect that those higher values will also be reflected in your brokerage account statements.
MS & Co. may, but is not obligated to, make a market in the securities, and, if it once chooses to make a market, may cease doing so at any time.

Dual Directional Trigger Participation Securities Based on the Value of the Worst Performing of the Russell 2000® Index and the S&P 500® Index due September 5, 2025
Principal at Risk Securities
Key Investment Rationale
The securities offer the potential for a positive return at maturity based on the absolute value of a limited range of percentage changes of the worst performing underlying index. At maturity, if the final index value of each underlying index is greater than its respective initial index value, investors will receive the stated principal amount of their investment plus a return reflecting 100% of the upside performance of the worst performing underlying index, subject to the maximum upside payment at maturity. If the final index value of either underlying index is less than or equal to its respective initial index value but the final index value of each underlying index is greater than or equal to its respective trigger level, investors will receive the stated principal amount of their investment plus a positive return based on the absolute value of the performance of the worst performing underlying index, which will be effectively limited to a 30% return. However, if the final index value of either underlying index is less than its respective trigger level, the absolute return feature will no longer be available and instead investors will be negatively exposed to the full decline in the worst performing underlying index and will lose 1% for every 1% decline in the worst performing underlying index over the term of the securities. Under these circumstances, the payment at maturity will be less than 70% of the stated principal amount and could be zero. Accordingly, you may lose your entire investment. All payments on the securities are subject to our credit risk.
Upside Scenario if Both Underlying Indices Appreciate 
Both underlying indices increase in value, and, at maturity, the securities redeem for the stated principal amount of $1,000 plus a return reflecting 100% of the index percent change of the worst performing underlying index, subject to the maximum upside payment at maturity of $1,350 to $1,400 per security (135% to 140% of the stated principal amount). The actual maximum upside payment at maturity will be determined on the pricing date. 
Absolute Return Scenario 
The final index value of either underlying index is less than or equal to its respective initial index value but the final index value of each underlying index is greater than or equal to its respective trigger level, which is 70% of its respective initial index value. In this case, you receive a 1% positive return on the securities for each 1% negative return on the worst performing underlying index. For example, if the final index value of the worst performing underlying index is 10% less than its respective initial index value, the securities will provide a total positive return of 10% at maturity. The maximum return you may receive in this scenario is a positive 30% return at maturity. 
Downside Scenario 
The final index value of either underlying index is less than its trigger level. In this case, the securities redeem for less than the stated principal amount by an amount proportionate to the full decline in the value of the worst performing underlying index over the term of the securities. For example, if the final index value of the worst performing underlying index is 70% less than its initial index value, the securities will be redeemed at maturity for a loss of 70% of the principal at $300, or 30% of the stated principal amount. There is no minimum payment at maturity on the securities, and investors may lose their entire initial investment. 
Because the payment at maturity of the securities is based on the worst performing of the underlying indices, a decline in either underlying index to less than its trigger level will result in a loss of a significant portion or all of your investment, even if the other underlying index has appreciated or has not declined as much.

Hypothetical Examples
The following hypothetical examples illustrate how to calculate the payment at maturity on the securities. The following examples are for illustrative purposes only. The actual initial index value and trigger level for each underlying index will be determined on the pricing date. Any payment at maturity on the securities is subject to our credit risk. The below examples are based on the following terms:
Stated principal amount: 
$1,000 per security 
Participation rate: 
100% 
Hypothetical maximum upside payment at maturity: 
$1,350 per security (135% of the stated principal amount) 
Hypothetical initial index value: 
With respect to the RTY Index: 2,100 With respect to the SPX Index: 4,000 
Hypothetical trigger level: 
With respect to the RTY Index: 1,470, which is 70% of its hypothetical initial index value With respect to the SPX Index: 2,800, which is 70% of its hypothetical initial index value 
EXAMPLE 1: Both underlying indices appreciate significantly and so investors receive only the maximum upside payment at maturity.
Final index value 

RTY Index: 3,990 



SPX Index: 7,200 

Index percent change 

RTY Index: (3,990 – 2,100) / 2,100 = 90% SPX Index: (7,200 – 4,000) / 4,000 = 80% 

Payment at maturity 
= 
$1,000 + ($1,000 × participation rate × index percent change of the worst performing underlying index), subject to the maximum upside payment at maturity 


= 
$1,000 + ($1,000 × 100% × 80%), subject to the maximum upside payment at maturity 


= 
maximum upside payment at maturity of $1,350 per security 
In example 1, the final index values of both the RTY Index and the SPX Index are significantly greater than their initial index values. The RTY Index has appreciated by 90%, while the SPX Index has appreciated by 80%. Therefore, investors receive at maturity the stated principal amount plus 100% of the appreciation of the worst performing underlying index, subject to the hypothetical maximum upside payment at maturity of $1,350 per security. Under the terms of the securities, investors will realize the hypothetical maximum upside payment at maturity at a final index value of the worst performing underlying index of 135% of its respective initial index value. Therefore, in this example, investors receive only the hypothetical maximum upside payment at maturity of $1,350 per stated principal amount, even though both underlying indices have appreciated significantly.
EXAMPLE 2: The final index value of each underlying index is greater than its respective initial index value.
Final index value 

RTY Index: 2,310 



SPX Index: 5,600 

Index percent change 

RTY Index: (2,310 – 2,100) / 2,100 = 10% SPX Index: (5,600 – 4,000) / 4,000 = 40% 

Payment at maturity 
= 
$1,000 + ($1,000 × participation rate × index percent change of the worst performing underlying index), subject to the maximum upside payment at maturity 


= 
$1,000 + ($1,000 × 100% × 10%), subject to the maximum upside payment at maturity

= 
$1,100 
In example 2, the final index values of both the RTY Index and SPX Index are greater than their initial index values. The RTY Index has appreciated by 10% while the SPX Index has appreciated by 40%. Therefore, investors receive at maturity the stated principal amount plus 100% of the appreciation of the worst performing underlying index, which is the RTY Index in this example. Investors receive $1,100 per security at maturity.
EXAMPLE 3: The final index value of one underlying index is greater than its respective initial index value while the final index value of the other underlying index is less than its respective initial index value but greater than its respective trigger level.
Final index value 

RTY Index: 2,310 



SPX Index: 3,200 

Index percent change 

RTY Index: (2,310 – 2,100) / 2,100 = 10% SPX Index: (3,200 – 4,000) / 4,000 = 20% 

Index performance factor 

RTY Index: 2,310 / 2,100 = 110% SPX Index: 3,200 / 4,000 = 80% 

Payment at maturity 
= 
$1,000 + ($1,000 × absolute index return of the worst performing underlying index) 


= 
$1,000 + ($1,000 × 20%) 


= 
$1,200 
In example 3, the final index value of the RTY Index is greater than its respective initial index value, while the final index value of the SPX Index is less than its respective initial index value but greater than its respective trigger level. While the RTY Index has appreciated by 10%, the SPX Index has declined by 20%. Therefore, investors receive at maturity the stated principal amount plus the absolute value of the performance of the worst performing underlying index, which is the SPX Index in this example. Investors receive $1,200 per security at maturity. In this example, investors receive a positive return even though one of the underlying indices declined in value by 20%, due to the absolute return feature of the securities and because neither underlying index declined beyond its respective trigger level.
EXAMPLE 4: The final index value of one underlying index is greater than its respective initial index value while the final index value of the other underlying index is less than its respective trigger level.
Final index value 

RTY Index: 2,310 



SPX Index: 2,000 

Index percent change 

RTY Index: (2,310 – 2,100) / 2,100 = 10% SPX Index: (2,000 – 4,000) / 4,000 = 50% 

Index performance factor 

RTY Index: 2,310 / 2,100 = 110% SPX Index: 2,000 / 4,000 = 50% 

Payment at maturity 
= 
$1,000 × index performance factor of the worst performing underlying index 


= 
$1,000 × 50% 


= 
$500 
In example 4, the final index value of the RTY Index is greater than its respective initial index value, while the final index value of the SPX Index is less than its respective trigger level. While the RTY Index has appreciated by 10%, the SPX Index has declined by 50%. Therefore, investors are exposed to the full negative performance of the SPX Index, which is the worst performing underlying index in this example, and receive a payment at maturity of $500 per security. In this example, investors are exposed to the negative performance of the worst performing underlying index even though the other underlying index has appreciated in value by 10%.

EXAMPLE 5: The final index value of each underlying index is less than its respective initial index value, but neither underlying index has decreased to below its respective trigger level.
Final index value 

RTY Index: 1,785 



SPX Index: 3,600 

Index percent change 

RTY Index: (1,785 – 2,100) / 2,100 = 15% SPX Index: (3,600 – 4,000) / 4,000 = 10% 

Payment at maturity 
= 
$1,000 + ($1,000 × absolute index return of the worst performing underlying index) 


= 
$1,000 + ($1,000 × 15%) 


= 
$1,150 
In example 5, the final index value of each underlying index is less than its respective initial index value, but neither underlying index has decreased to below its respective trigger level. The RTY index has declined by 15% while the SPX Index has declined by 10%. Therefore, investors receive at maturity the stated principal amount plus the absolute value of the performance of the worst performing underlying index, which is the RTY Index in this example. Investors receive a payment at maturity of $1,150 per security.
EXAMPLE 6: The final index value of each underlying index is less than its respective trigger level.
Final index value 

RTY Index: 630 



SPX Index: 1,600 

Index percent change 

RTY Index: (630 – 2,100) / 2,100 = 70% SPX Index: (1,600 – 4,000) / 4,000 = 60% 

Index performance factor 

RTY Index: 630 / 2,100 = 30% SPX Index: 1,600 / 4,000 = 40% 

Payment at maturity 
= 
$1,000 × index performance factor of the worst performing underlying index 


= 
$1,000 × 30% 


= 
$300 
In example 6, the final index values of both the RTY Index and the SPX Index are less than their respective trigger levels. The RTY index has declined by 70% while the SPX Index has declined by 60%. Therefore, investors are exposed to the full negative performance of the RTY Index, which is the worst performing underlying index in this example, and receive a payment at maturity of $300 per security.
Because the payment at maturity of the securities is based on the worst performing of the underlying indices, a decline in either underlying index to below its respective trigger level will result in a loss of a significant portion or all of your investment, even if the other underlying index has appreciated or has not declined as much.

Principal at Risk Securities
Risk Factors
This section describes the material risks relating to the securities. For further discussion of these and other risks, you should read the section entitled “Risk Factors” in the accompanying product supplement for participation securities, index supplement and prospectus. We also urge you to consult your investment, legal, tax, accounting and other advisers in connection with your investment in the securities.
Risks Relating to an Investment in the Securities
￭The securities do not pay interest and do not guarantee any return of principal at maturity. The terms of the securities differ from those of ordinary debt securities in that the securities do not pay interest and do not guarantee any return of principal at maturity of the securities. If the final index value of either underlying index is less than its respective trigger level, the absolute return feature will no longer be available and you will instead receive for each security that you hold a payment at maturity that is significantly less than the stated principal amount of each security by an amount proportionate to the decline in the value of the worst performing underlying index from its initial index value. There is no minimum payment at maturity on the securities, and, accordingly, you could lose your entire initial investment.
￭The appreciation potential of the securities is limited by the maximum upside payment at maturity. The appreciation potential of the securities is limited by the maximum upside payment at maturity of $1,350 to $1,400 per security, or 135% to 140% of the stated principal amount. Because the payment at maturity will be limited to 135% to 140% of the stated principal amount of the securities if both underlying indices appreciate, any increase in the final index value of the worst performing underlying index over its initial index value by more than 35% to 40% of its initial index value will not further increase the return on the securities. The maximum return you can realize if the worst performing underlying index depreciates is also limited because of the respective trigger level. If the worst performing underlying index depreciates to below its respective trigger level, you will lose a significant portion or all of your investment in the securities.
￭The market price of the securities will be influenced by many unpredictable factors. Several factors will influence the value of the securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the securities in the secondary market, including the value, volatility and dividend yield of the underlying indices, interest and yield rates in the market, time remaining until the securities mature, geopolitical conditions and economic, financial, political, regulatory or judicial events and any actual or anticipated changes in our credit ratings or credit spreads. The levels of the underlying indices may be, and have recently been, volatile, and we can give you no assurance that the volatility will lessen. See “Russell 2000® Index Overview” and “S&P 500® Index Overview” below. You may receive less, and possibly significantly less, than the stated principal amount per security if you try to sell your securities prior to maturity.
￭The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities. You are dependent on our ability to pay all amounts due on the securities at maturity and therefore you are subject to our credit risk. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the securities prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the securities.
￭As a finance subsidiary, MSFL has no independent operations and will have no independent assets. As a finance subsidiary, MSFL has no independent operations beyond the issuance and administration of its securities and will have no independent assets available for distributions to holders of MSFL securities if they make claims in respect of such securities in a bankruptcy, resolution or similar proceeding. Accordingly, any recoveries by such holders will be limited to those available under the related guarantee by Morgan Stanley and that guarantee will rank pari passu with all other unsecured, unsubordinated obligations of Morgan Stanley. Holders will have recourse only to a single claim against Morgan Stanley and its assets under the guarantee. Holders of securities issued by MSFL should accordingly assume that in any such proceedings they would not have any priority over and should be treated pari passu with the claims of other unsecured, unsubordinated creditors of Morgan Stanley, including holders of Morgan Stanleyissued securities.
￭The amount payable on the securities is not linked to the values of the underlying indices at any time other than the valuation date. The final index value of each underlying index will be based on the index closing value of such index on the valuation date, subject to postponement for nonindex business days and certain market disruption events. Even if both underlying indices appreciate prior to the valuation date but the value of either underlying index drops by the valuation date to

less than its respective trigger level, the payment at maturity may be significantly less than it would have been had the payment at maturity been linked to the values of the underlying indices prior to such drop. Although the actual values of the underlying indices on the stated maturity date or at other times during the term of the securities may be higher than their respective final index values, the payment at maturity will be based solely on the index closing values on the valuation date.
￭Investing in the securities is not equivalent to investing in either underlying index. Investing in the securities is not equivalent to investing in either underlying index or the component stocks of either underlying index. As an investor in the securities, you will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to stocks that constitute either underlying index.
￭The rate we are willing to pay for securities of this type, maturity and issuance size is likely to be lower than the rate implied by our secondary market credit spreads and advantageous to us. Both the lower rate and the inclusion of costs associated with issuing, selling, structuring and hedging the securities in the original issue price reduce the economic terms of the securities, cause the estimated value of the securities to be less than the original issue price and will adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the prices, if any, at which dealers, including MS & Co., may be willing to purchase the securities in secondary market transactions will likely be significantly lower than the original issue price, because secondary market prices will exclude the issuing, selling, structuring and hedgingrelated costs that are included in the original issue price and borne by you and because the secondary market prices will reflect our secondary market credit spreads and the bidoffer spread that any dealer would charge in a secondary market transaction of this type as well as other factors.
The inclusion of the costs of issuing, selling, structuring and hedging the securities in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the securities less favorable to you than they otherwise would be.
However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 6 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying indices, and to our secondary market credit spreads, it would do so based on values higher than the estimated value, and we expect that those higher values will also be reflected in your brokerage account statements.
￭The estimated value of the securities is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no marketstandard way to value these types of securities, our models may yield a higher estimated value of the securities than those generated by others, including other dealers in the market, if they attempted to value the securities. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your securities in the secondary market (if any exists) at any time. The value of your securities at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also “The market price of the securities will be influenced by many unpredictable factors” above.
￭The securities will not be listed on any securities exchange and secondary trading may be limited. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. MS & Co. may, but is not obligated to, make a market in the securities and, if it once chooses to make a market, may cease doing so at any time. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the securities, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Since other brokerdealers may not participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which MS & Co. is willing to transact. If, at any time, MS & Co. were to cease making a market in the securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.
￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the securities. One or more of our affiliates and/or thirdparty dealers expect to carry out hedging activities related to the securities (and possibly to other instruments linked to the underlying indices or their component stocks), including trading in the stocks that constitute the underlying indices as well as in other instruments related to the underlying indices. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the valuation date approaches. Some of our affiliates also trade the stocks

that constitute the underlying indices and other financial instruments related to the underlying indices on a regular basis as part of their general brokerdealer and other businesses. Any of these hedging or trading activities on or prior to the pricing date could potentially affect the initial index value of either underlying index, and, therefore, could increase the trigger level for such underlying index, which is the value at or above which such underlying index must close on the valuation date so that investors do not suffer a significant loss on their initial investment in the securities (depending also on the performance of the other underlying index). Additionally, such hedging or trading activities during the term of the securities, including on the valuation date, could adversely affect the closing value of either underlying index on the valuation date and, accordingly, the amount of cash an investor will receive at maturity, if any (depending also on the performance of the other underlying index).
￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities. As calculation agent, MS & Co. will determine the initial index values, the trigger levels and the final index values, including whether any underlying index has decreased to below its respective trigger level, and will calculate the amount of cash, if any, you receive at maturity. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or nonoccurrence of market disruption events and the selection of a successor index or calculation of the final index value in the event of a market disruption event or discontinuance of an underlying index. These potentially subjective determinations may adversely affect the payout to you at maturity, if any. For further information regarding these types of determinations, see “Description of Securities—Postponement of Valuation Date(s),” “—Alternate Exchange Calculation in case of an Event of Default” and “—Calculation Agent and Calculations” and related definitions in the accompanying product supplement. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.
￭The U.S. federal income tax consequences of an investment in the securities are uncertain. Please read the discussion under “Additional Information—Tax considerations” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for participation securities (together, the “Tax Disclosure Sections”) concerning the U.S. federal income tax consequences of an investment in the securities. If the Internal Revenue Service (the “IRS”) were successful in asserting an alternative treatment, the timing and character of income on the securities might differ significantly from the tax treatment described in the Tax Disclosure Sections. For example, under one possible treatment, the IRS could seek to recharacterize the securities as debt instruments. In that event, U.S. Holders would be required to accrue into income original issue discount on the securities every year at a “comparable yield” determined at the time of issuance and recognize all income and gain in respect of the securities as ordinary income. The risk that financial instruments providing for buffers, triggers or similar downside protection features, such as the securities, would be recharacterized as debt is greater than the risk of recharacterization for comparable financial instruments that do not have such features. We do not plan to request a ruling from the IRS regarding the tax treatment of the securities, and the IRS or a court may not agree with the tax treatment described in the Tax Disclosure Sections.
In 2007, the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require holders of these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; whether shortterm instruments should be subject to any such accrual regime; the relevance of factors such as the exchangetraded status of the instruments and the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by nonU.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” rule, which very generally can operate to recharacterize certain longterm capital gain as ordinary income and impose an interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. Both U.S. and NonU.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, the issues presented by this notice and any tax consequences arising under the laws of any state, local or nonU.S. taxing jurisdiction.
Risks Relating to the Underlying Indices
￭You are exposed to the price risk of both underlying indices. Your return on the securities is not linked to a basket consisting of both underlying indices. Rather, it will be based upon the independent performance of each underlying index. Unlike an instrument with a return linked to a basket of underlying assets, in which risk is mitigated and diversified among all the components of the basket, you will be exposed to the risks related to both underlying indices. Poor performance by either underlying index over the term of the securities will negatively affect your return and will not be offset or mitigated by any

positive performance by the other underlying index. If either underlying index declines to below its trigger level, equal to 70% of its respective initial index value, as of the valuation date, you will lose a significant portion or all of your investment, even if the other underlying index has appreciated or has not declined as much. Accordingly, your investment is subject to the price risk of both underlying indices.
￭Because the securities are linked to the performance of the worst performing underlying index, you are exposed to a greater risk of sustaining a significant loss on your investment than if the securities were linked to just one underlying index. The risk that you will suffer a significant loss on your investment is greater if you invest in the securities as opposed to substantially similar securities that are linked to the performance of just one underlying index. With two underlying indices, it is more likely that either underlying index will decline to below its trigger level as of the valuation date than if the securities were linked to only one underlying index. Therefore it is more likely that you will suffer a significant loss on your investment.
￭The securities are linked to the Russell 2000® Index and are subject to risks associated with smallcapitalization companies. As the Russell 2000® Index is one of the underlying indices, and the Russell 2000® Index consists of stocks issued by companies with relatively small market capitalization, the securities are linked to the value of smallcapitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than largecapitalization companies and therefore the Russell 2000® Index may be more volatile than indices that consist of stocks issued by largecapitalization companies. Stock prices of smallcapitalization companies are also more vulnerable than those of largecapitalization companies to adverse business and economic developments, and the stocks of smallcapitalization companies may be thinly traded. In addition, small capitalization companies are typically less wellestablished and less stable financially than largecapitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than largecapitalization companies and are more susceptible to adverse developments related to their products.
￭Adjustments to the underlying indices could adversely affect the value of the securities. The publisher of either underlying index may add, delete or substitute the stocks constituting such underlying index or make other methodological changes that could change the value of such underlying index. The publisher of either underlying index may discontinue or suspend calculation or publication of such underlying index at any time. In these circumstances, the calculation agent will have the sole discretion to substitute a successor index that is comparable to the discontinued underlying index and will be permitted to consider indices that are calculated and published by the calculation agent or any of its affiliates.

Tax considerations: 
Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the securities due to the lack of governing authority, in the opinion of our counsel, Davis Polk & Wardwell LLP, under current law, and based on current market conditions, a security should be treated as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. However, because our counsel’s opinion is based in part on market conditions as of the date of this document, it is subject to confirmation on the pricing date. Assuming this treatment of the securities is respected and subject to the discussion in “United States Federal Taxation” in the accompanying product supplement for participation securities, the following U.S. federal income tax consequences should result based on current law: ￭A U.S. Holder should not be required to recognize taxable income over the term of the securities prior to settlement, other than pursuant to a sale or exchange. ￭Upon sale, exchange or settlement of the securities, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized and the U.S. Holder’s tax basis in the securities. Such gain or loss should be longterm capital gain or loss if the investor has held the securities for more than one year, and shortterm capital gain or loss otherwise. In 2007, the U.S. Treasury Department and the Internal Revenue Service (the “IRS”) released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require holders of these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; whether shortterm instruments should be subject to any such accrual regime; the relevance of factors such as the exchangetraded status of the instruments and the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by nonU.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” rule, which very generally can operate to recharacterize certain longterm capital gain as ordinary income and impose an interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. As discussed in the accompanying product supplement for participation securities, Section 871(m) of the Internal Revenue Code of 1986, as amended, and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% (or a lower applicable treaty rate) withholding tax on dividend equivalents paid or deemed paid to NonU.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (each, an “Underlying Security”). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a “Specified Security”). However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2023 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the securities and current market conditions, we expect that the securities will not have a delta of one with respect to any Underlying Security on the pricing date. However, we will provide an updated determination in the final pricing supplement. Assuming that the securities do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the securities should not be Specified Securities and, therefore, should not be subject to Section 871(m).

Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If withholding is required, we will not be required to pay any additional amounts with respect to the amounts so withheld. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities. Both U.S. and nonU.S. investors considering an investment in the securities should read the discussion under “Risk Factors” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for participation securities and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, the issues presented by the aforementioned notice and any tax consequences arising under the laws of any state, local or nonU.S. taxing jurisdiction. The discussion in the preceding paragraphs under “Tax considerations” and the discussion contained in the section entitled “United States Federal Taxation” in the accompanying product supplement for participation securities, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the securities. 









Use of proceeds and hedging: 
The proceeds from the sale of the securities will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per security issued, because, when we enter into hedging transactions in order to meet our obligations under the securities, our hedging counterparty will reimburse the cost of the agent’s commissions. The costs of the securities borne by you and described beginning on page 2 above comprise the agent’s commissions and the cost of issuing, structuring and hedging the securities. On or prior to the pricing date, we will hedge our anticipated exposure in connection with the securities by entering into hedging transactions with our affiliates and/or thirdparty dealers. We expect our hedging counterparties to take positions in stocks of the underlying indices, futures and/or options contracts on the underlying indices, any component stocks of the underlying indices listed on major securities markets or positions in any other available securities or instruments that they may wish to use in connection with such hedging. Such purchase activity could potentially increase the value of either underlying index on the pricing date, and therefore could increase the trigger level for such underlying index, which is the level at or above which such underlying index must close on the valuation date so that investors do not suffer a significant loss on their initial investment in the securities (depending also on the performance of the other underlying index). In addition, through our affiliates, we are likely to modify our hedge position throughout the term of the securities, including on the valuation date, by purchasing and selling the stocks constituting the underlying indices, futures or options contracts on the underlying indices or its component stocks listed on major securities markets or positions in any other available securities or instruments that we may wish to use in connection with such hedging activities. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the valuation date approaches. We cannot give any assurance that our hedging activities will not affect the value of either underlying index, and, therefore, adversely affect the value of the securities or the payment you will receive at maturity, if any (depending also on the performance of the other underlying index). For further information on our use of proceeds and hedging, see “Use of Proceeds and Hedging” in the accompanying product supplement for participation securities.
